Patent DE-3802017-A1 (DE)
Title: Automatic adjusting device for a disc brake
Inventor: HENEIN NABIL
IPC: F16D65/56
Filed: 1988-01-25
Abstract: The object of the invention is, in an adjusting device for a hydraulically and mechanically actuable disc brake, to ensure simplicity of support for the turning spindle, which is arranged essentially fixed. The invention solves this problem by using a wire bending spring (20) which latches onto the end (24) of the spindle protruding from the housing (22). The construction of the spring enables the spindle (18) to be installed and removed in a simple manner and, in addition to providing support in the axial direction, the spring (20) prevents the spindle (18) from executing a rotary motion about the longitudinal axis. <IMAGE>

Title: Feed control device for pile transportation
Inventor: WAGNER BURKHARD
IPC: B65H5/24
Filed: 1988-02-05
Abstract: The feed control device for pile transportation is used for controlling the transporting speed of sheet piles, fanned out in an imbricated formation, onto round pile deliverers. By means of the device according to the invention, the transporting feed is regulated with adaptation to a greater sheet advance within the sheet pile. For this purpose, the position of the sheet edge of the uppermost sheet (1) is scanned by a feeler lever (3), the signal is transmitted, amplified and stored. Controlled by the machine cycle, it acts via an actuator (20) on the pile transporting motor (21), as a result of which the speed is fixed at which the following sheet is transported to a sheet withdrawal device (2). <IMAGE>

Title: Pot-like container with a removable lid
Inventor: CREYAUFMUELLER PETER
IPC: B65D6/12
Filed: 1988-03-10
Abstract: A pot-like container (1) having a removable lid (2), in particular for use in the household as a freshness-maintaining, freezing or storage container, is to be designed using simple means in such a way as to allow adaptation of the container volume to different filling quantities. For this purpose, provision is made for the spacing between the container bottom (8) and the terminating lid surface (9) to be designed to be variable, specifically by an amount which is considerably greater than the overall lid height. In the exemplary embodiment, a cylindrical insert (3) with an external thread (4) is provided for this purpose, which insert can be screwed to a greater or lesser depth into the container (1) provided with an internal thread (5). Depending on the screwing-in height, the usable volume of the container (1) changes. <IMAGE>

Title: Extendable protective covering for the side windows of cars, integrated with the sheet-type roof covering
Inventor: RIECK WOLFGANG
IPC: B60J11/00
Filed: 1988-04-12
Abstract: The known sheet-type roof covering for cars offers protection against the sun and rain from the roof side. The side windows are in this case unprotected. The invention integrates the side-window covering with the sheet-type roof covering. For this purpose, the core piece, the roller-blind shaft, is kept thinner at the two ends than the shaft itself. This has the advantage that the folding parts, which are attached to the two sides of the sheet, can position themselves on these thinner ends of the shaft when the roof sheet is being rolled up and lie flat with the roof sheet. On unrolling the roof sheet the folding parts are lowered and, in the process, cover the side windows of the car down to the door handles. On rolling back the roof sheet the folding parts again position themselves on the thinner shaft ends and together with the roof sheet again form a closed roller-blind. An umbrella-type linkage incorporated into the folding parts ensures that the folding parts fold and unfold readily.

Title: Control unit for the grinding device of a rotation hoop knife splitting machine
Inventor: LASSNIG HANS
IPC: B26D7/12
Filed: 1988-05-04
Abstract: A control unit for the grinding device of a rotation hoop knife splitting machine receives a signal representing the grinding intensity, preferably a signal proportional to the current consumption of a grinding motor (95) which drives the grinding discs, and a time signal. From these values, the control unit forms a criterion which, when it exceeds a maximum value which is or can be predetermined, indicates that a trimming operation is necessary for the grinding discs, and carries this out. As criterion for the necessity of a trimming operation, use can be made in particular of the product of the instantaneous grinding intensity and the grinding time which has passed since the last trimming operation or the sum <IMAGE>  where  Sakt.n is the instantaneous grinding intensity and tinc is a fixed or variable time interval. Under certain circumstances, the grinding time alone is adequate as criterion (Fig. 9). <IMAGE>

The outputs (11, 12) of the differential amplifiers are led together via an isolating stage (13), whose output (14) is connected with the respective second input (16, 17) of the differential amplifiers. <IMAGE>
Patent DE-3819666-A1 (DE)
Inventor: MOUNTFORD EDWARD HENRY
IPC: B25B11/00

Abstract: A curved, scratched window to be refurbished is placed against a plate 10 with either its convex or concave side facing the plate such that a flexible lip seal 24 protruding from the front face of the plate is engaged by the window. A vacuum is then applied to a network of channels 26 of the plate 10 to pull the window flat against the plate 10 and cause the window to push the lip seal 24 flush with the surface of the plate. The plate 10 is then rotated about an axis 20 and a tool carrier 22 is moved across the surface of the plate along the phantom line 38 such that three diamond tools remove a portion of the surface of the window. <IMAGE>

Title: Circuit arrangement for DC controller operation of an electric motor in the driving mode and braking mode
Inventor: KIRCHNER HANS-JOACHIM DIPL ING
IPC: B60L9/04
Filed: 1988-08-03
Abstract: The invention relates to a circuit arrangement for DC controller operation of an electric motor in the driving mode and braking mode, having a main thyristor for the driving mode and a braking thyristor, which is polarised in the same direction, for resistance braking, which thyristor is connected in parallel with the main thyristor, in series with a coupling diode of opposite polarity. A common, parallel turn-off path with a semiconductor valve which can be switched off is provided, an additional capacitor which is precharged to a defined voltage and has a greater capacitance being connected in parallel with the circuitry capacitor in order to limit the voltage rise on the circuitry capacitor when the semiconductor valve is switched off, as soon as the charging voltage on the circuitry capacitor exceeds the defined value. In the driving mode, the additional capacitor is discharged in a pulsed manner and, in resistance braking operation, the braking current flows either via the braking thyristor or via the coupling diode. In order that the additional capacitor can discharge easily during the "mains-isolated braking" operating mode without any discharging resistor loading the mains in the other operating modes, it is proposed that the divider point between the additional capacitor (Cz) and the coupling valve (V11) be connected to the braking diode (BD) via a discharge resistor (Rz), which permits a discharging reverse current for the additional capacitor (Cz) in braking operation, in the event of a forward current via the braking diode (BD). <IMAGE>
